Symbolize by Chart

获得 Business Analyst 许可后可用。

描述

Thematically maps a feature class based on a numeric field and displays it as a symbolized chart

使用方法

  • Charts can be effective for comparing several values at once. For example, you could display ZIP Codes as a pie chart, with each wedge representing population by race.

  • Compares only a few areas (20 or 30 at most).

  • Use five or less categories on your chart.

  • Make sure the values between points vary enough to show differences.
